About the slider and keyboard

The slider enables you to use your
BlackBerry® device when it is open or closed. For
example, when
the slider is closed, you
can use the touch screen keyboard to type short
responses to messages. When the slider is open, the slide-out
keyboard is available for you
to type longer messages, access
keyboard shortcuts, and
type
while you view a full screen of content.
You can also open the slider to answer a call and to turn on backlighting.

You
can use the
touch screen keyboard in
either portrait or landscape view. If you open the slider when the touch screen
keyboard is displayed, the touch screen keyboard disappears
and the device displays screens in portrait view.
Videos
are displayed
according to your device's orientation.
